How often do you trip when you walk down the street? How often do you bump into objects or drop important items? If you are clumsy, it may perhaps be more often than others, but it can certainly not be more often than you do when you are at home.
It is quite strange that although our home is a familiar space, we seem to bump into furniture, drop objects and misplace our things more often than we do when we are in unfamiliar places, like the street or a shop. We may not notice this phenomenon, nor may it seem particularly important, but it is a rather candid reflection of a slice of human nature.
